If you intend to provide heat to your manifold, you will need to drill a hole in the center of one or both of these fittings and run a tube up to the exhaust passages within the intake manifold. If you do not need to heat your intake, do not drill the holes. If using the stock clamps, it would be necessary to use shorter studs because of the thickness of the flange on these headers compared to the stock cast iron manifolds. An aftermarket intake manifold would also complicate the stud or bolt length requirements.
A spacer may be required to match up the thickness variations between the intake and exhaust manifolds.
